When to call us in Tolleshunt Knights
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Signs it’s time to call us include:
- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
- Leaking joints around cladding and façade panels
Rented homes near Kelvedon station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

External mastic for homes and businesses in Tolleshunt Knights
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on concrete & block, façade panels and brickwork movement joints, and the jobs we see most are plants rooting in failed movement joints and joints where the bead has come unstuck.
Around Tolleshunt Knights, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
Every job is covered by a 12-month guarantee.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Fix overflowing gutters above sealed joints
- Check the sealant is paintable before painting near it
- Avoid pressure-washing directly into sealant joints
- Never let anyone fill a movement joint with mortar
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. In a small place like Tolleshunt Knights, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions

Advice
Why it’s worth doing now in Tolleshunt Knights
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like Tolleshunt Knights, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
Why book with us
- Over 20 years’ experience
- Approved under the ARBOMaster scheme
- Anti-fungal sanitary silicone in wet areas
- White, clear, grey or coloured to suit, where the product allows

What external mastic looks like in Tolleshunt Knights
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Layer Marney Tower (about 2 miles north-east) nearby, there’s older building stock in the area around Tolleshunt Knights as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of All Saints include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as St Luke's Church of England Controlled Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Different surfaces, different methods
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. We reseal them with a sealant suited to the panel material.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two.
